All,
I am testing Yinghai's patch based on 3.13-rc1, after applying these four
patches, there is an error during probe for mlx4_core.
Code base we did the test:
$ git oneline -5
298a335 PCI: Try best to allocate pref mmio 64bit above 4g
b730e81 PCI: Try to allocate mem64 above 4G at first
4e27325 PCI: Don't use 4G bus address directly in resource allocation
ab6c20f PCI: pcibus address to resource converting take bus instead of dev
6ce4eac Linux 3.13-rc1
Error log:
mlx4_core 0003:05:00.0: Multiple PFs not yet supported. Skipping PF.
mlx4_core: probe of 0003:05:00.0 failed with error -22
My analysis:
After careful investigation, I guess this error is not introduced by
Yinghai's patch. This looks more like an error from device itself. Since
this error really happens after applying Yinghai's patch(especially the last
one 298a335), I would like to include Yinghai in this loop.
Sorry, can you provide pointers please? I don't see 298a335 on Linus
3.13-rc8+ tree nor in net-next,
$ git log --oneline --author=Yinghai v3.12..
e7cc5cf PCI: Remove duplicate pci_disable_device() from
pcie_portdrv_remove()
cf3e1fe PCI: Workaround missing pci_set_master in pci drivers
bee7f9c ACPI / x86: Increase override tables number limit

So are you referring to patches on the PCI development tree
git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git "next"
branch? which
Or.
